It seems I may need to replace my temp II sensor on my 1989 Vanagon GL.

I searched the archives and found some good information but nothing on how
to do it.

Being still relatively ignorant about the  procedure I ned to know specifics
about how to remove and replace the old sensor. Simple questions like does
it screw in? Plug in? What tools do I need?
